What is better: spray, roll-on or solid deodorant?
Actually, if you are concerned with excessive armpit sweat, you need to use an antiperspirant, not a deodorant. Antiperspirants contain aluminum as an active ingredient. When the aluminum ions travel into the cells of your sweat glands, they take moisture with them. Soon enough water has gone into the cells to cause them to swell shut, effectively stopping sweat from coming out. Deodorant, on the other hand, contains ingredients that neutralize the odors caused by bacterial action on sweat, either by fighting the bacteria directly or covering up the odor with a fragrance, or both. A lot of the personal hygiene products available today contain both antiperspirant and deodorant ingredients. There is no difference between the spray, roll-on or solid formulations in terms of whether one works better than the other. You can feel free to use whichever is most comfortable and works with your lifestyle the best.
